Top-heaviness is gone, here comes the world's lightest bass tuner! Gear ratio 1:22.

A special female screw guarantees precise positioning and fixing of the shaft.

Measure specifications

All measurements in the product catalogue are given in mm (inch), unless a different unit of measurement is stated.

 

Technical drawings and operating instructions

We do not accept any liability for the correctness of the technical drawings. Prior to installation, please measure for yourself once more, so you can consider regular manufacturing tolerances.

Please note that the technical data can also vary slightly, depending on the surface color. This is due to the difference in the galvanic coating and the galvanic layering, which depends on the color (nickel, chrome etc).

The technical drawings can be printed on one page width. Should the technical drawings not fit on one page, however, please check your print page setup (note: they can be several pages long).

From time to time, the measurements given in the file downloads on our website may differ from those given in the catalogue. Please bear in mind that the measurements given in the online downloads are current. Any discrepancies will be corrected when the catalogue is updated.

Machine Heads combination

Here are all conceivable combinations of left and right tuning heads and the desired numbers of each which are available to order.
All machine heads and buttons can also be ordered individually. All conceivable combinations are depicted here, irrespective of the type of guitar or bass.

Every other possible combination for 8-string / 12-string instruments etc. is also possible, of course.

For the sake of simplicity, the images show only one machine head of the relevant type, either as a left or right-side model. This means that a right-side machine head model may be depicted for the "6-in-line" combination; in such cases, however, the machine head can of course be ordered both as a left and right-side model.

Shafts for classical machine heads

The use of the different shafts enables the classic machine heads to be adapted to the various instrument head plates. The right shafts are used for metal and gut/synthetic strings.  

Classical guitar and mandolin machine heads come with four different types of shaft:

1 = Nylon-shaft (brass with a plastic sleeve)
2 = Emberger shaft
3 = Gibson shaft
4 = Emberger shaft (brass with a plastic sleeve)

Shafts "2", "3" and "4" require the use of thrust bearings.

Shaft type 1 for Lyra and Hauser machine heads varies slightly from shaft type 1 for standard machine heads.

This image shows the different types of shaft and the choice of finishes available (nickel, chrome, gold, nylon shaft in white and black):

Schaller shafts for acoustic machine heads

All shafts can also generally be supplied in the eight different surface finishes available (see above).

 

Unless your order specifies otherwise, we deliver the following shafts as standard:

FAQ

FAQ10001 Can I also get machine heads in a 5/1 or 4/2 configuration?
For the sake of clarity, we have only illustrated the standard layouts. Naturally, every other combination (5/1, 4/2 etc.) can also be ordered via your retailer.

…in addition to this, individual machine heads, sets of buttons etc. can also be ordered.
FAQ10010 How can you tell the difference between left-side and right-side machine heads?
A simple way to tell the difference is to place a machine head in front of you so that the back of the housing is facing towards you and the button is pointing upwards. If the worm gear and button are then on the left of the housing, then it is a left-side machine head, e.g. as found on a Stratocaster.
FAQ10020 I know that you produce machine heads for many reputable manufacturers such as Fender, Gibson, PRS, etc. with their company logo. What can I do, if one of these machine heads breaks?
Unfortunately we are not allowed to provide you with a replacement part. Please contact the manufacturer directly. Alternatively, we can only recommend you to install a set of Schaller machine heads from your specialist dealer. Then you will always have 100% quality - since today, unfortunately, almost all manufacturers also use products with their logo from the Far East.
FAQ10030 Where can I find information on the required hole diameters on the head plate for Schaller machine heads?

On our website, under "Products/Product help/Guidelines", we have set up a table from which you can see the relevant measures for your machine heads.

Under "Products" and then in the detailed view you will of course find a detailed table for each of our products, showing the bore diameter in one of the columns.

The "Technical drawings" tab in the product details view gives you access to full technical drawings of the product in question, complete with all dimensions. These drawings can also be downloaded.

FAQ10040 Where can I find information on the different mounting options of your machine heads (bracket, pin, etc.)?

On our website, under "Products/Product help/Guidelines", we have set up a table from which you can see the respective designs.

FAQ10050 What do I need to consider when using Schaller machine heads "6 in line" for my left-handed guitar?
Please order 6 right or 6 left machine heads, depending on your preference and the arrangement on the head plate.
FAQ10060 Which are the methods available for mounting Schaller machine heads onto the head plate?

There are 3 methods:

  1. Fastening with screws with or without thrust bearing;
  2. Fastening with screws and banjo bold. Here, the banjo bolt is an additional fastening and thrust bearing at the same time.
  3. Fastening only with banjo bolt and pin.

The pin or pins (2 in our Fender machine heads) are only used to prevent machine head twisting. See also the reference table under Products/Product help/Guidlines.

FAQ10065 In your product catalog, what does the transmission ratio mean for the machine heads?
If, for example, you have a machine head with a transmission ratio of 1:16, this means that you will have to turn the button 16 times to turn the adjusting axis once.
FAQ10070 After several years of use my machine heads are hard to turn; what can I do?

We recommend the following procedure:

  1. Change the mounting screw of the button.
  2. Check the plastic or wave washer at the button for wear and renew if required.
  3. With the machine heads closed, carefully oil with light precision mechanics oil at the shaft or gears, with the machine heads open, carefully oil the mechanical parts.
FAQ10080 I saw machine heads bearing the "S" from Schaller and "Made in Germany" on the D-Tuner device from the U.S. company Hipshot. How's that?
We produce the machine heads for Hipshot, while Hipshot produces the "D-Tuner" itself, but the machine heads are original Schaller parts.
FAQ10090 Schaller supplies the classic machine heads with acrylic and plastic buttons. What is the difference between the materials and the processing?
The acrylic button is a high-quality plastic which is made from layered material in an elaborate process. Its structure is based on that of mother-of-pearl. The colors are homogenous, i.e. not painted. The plastic buttons are used for "standard" machine heads and are made by injection molding using high quality plastics.
FAQ10100 I have seen "I", "II" und "III" symbols or markings on the inside of the Schaller machine heads. What do they mean?
These markings have no significance at all for you or for the function of the Schaller machine head. For us they designate the individual machine molds so that we are better able to isolate the cause of a problem in the event of a material defect. Of course, no product leaves the Schaller premises without having been checked and approved by our multi-stage quality control.
FAQ10110 Can I modify machine heads myself and, if yes, which ones in order to to be able to use left machine heads as right machine heads and vice versa?
This is only possible in isolated cases with some bass machine heads. We do not generally recommend such practices, however, because the product specifics are usually not taken into consideration and this can lead to defective assembly.
FAQ10120 I need machine heads for my concert guitar with a 36mm wave washer and not the normal 35mm. What do I do?
In this particular case we recommend you use our MK MINI Series without the base plate. This way you have high quality machine heads and can select the shaft distance as you wish. You can use shafts for steel or nylon strings.
FAQ10130 I am looking for "Reverse Headstock" machine heads, and instead of the normal 6 left, I need 6 right machine heads. Where can I get them?

Please simply order them from a specialist dealer. We can easily supply any combination, including 6 right machine heads (please see under Products/Product help/Guidelines).

FAQ10140 How exactly is the Schaller Banjo tension peg B4 adjustable?

It works like a D-tuner. You tune a note, setting it with a knurled thumb screw. With the second knurled thumb screw you adjust the required deeper string note. When you loosen the 1st knurled thumb screw the machine head then automatically turns to the second set note.

FAQ10145 What is the difference between the B4 and B4 Excenter banjo machine heads?

The 'excentrical' offset form of the B4 Excenter machine head provides increased flexibility when fitting it to the headstock. A further difference is that it has a 1:3.5 gear ratio, as opposed to 1:4. This makes tuning your instrument quicker, easier AND more precise!

FAQ10150 What does Schaller recommend for cleaning the tarnished tuning buttons on chrome-plated bass machine heads?
A difficult one: give it a careful try with a chrome polish. If the buttons are already too heavily tarnished, usually due to hand perspiration, then replacement is the only option.
FAQ10160 How do the Schaller clamp machine heads / locking tuners work?

These function like normal tuners but you do not need to wrap the strings around the shaft at the beginning. You position the string in the shaft hole with the clamp screw loosened, shorten the string approx. 10 mm behind the shaft, clamp the string with the clamp screw and tune the string (please see under Service/Lexicon).

FAQ10170 How can I clean Schaller BM Light machine heads with plastic housing?
Our plastic is reinforced with carbon fiber, so you can clean them using car polish or key oil.
FAQ10180 I have two sets of Schaller machine heads, but I have realized that the buttons are of different sizes.
Our tuning heads are fitted as standard with large buttons for 3/3 configuration and small buttons for 6-in-line configuration.
FAQ10190 Can I fit a set of Schaller "mini" machine heads with the buttons from a set of normal-sized machine heads?
Yes, you can do that - the shaft has the same diameter, so you just need a longer screw. However, you need to pay attention to the appearance and to the spacing between the machine heads, which they require in order to turn and which obviously becomes smaller.
FAQ10200 Can I also order individual machine heads or just the buttons?
Yes, you can also order any machine head individually, or just a set of buttons without the machine heads.
FAQ10220 Are the screws supplied for fixing the buttons to the housing the same color as the buttons?
In general yes, except in cases such as bicolor products or ebony buttons.
FAQ10230 I have fitted Schaller M6 locking machine heads to a Gibson headstock which is very thick; the problem is that the shaft with the hole only protrudes very slightly. What can I do about this?
In such cases, please order our Schaller M6 2000 locking machine heads with the special shaft length, which is 21mm rather than 18.5 or 19.5mm (staggered).
FAQ10240 Can I use steel strings with Schaller's acoustic guitar machine heads?

Yes, you can. Our machine heads are designed for this purpose. Please use either the Gibson or Emberger-type shaft (see Products/Guideline). For our nylon shafts, we recommend using nylon or gut strings.

FAQ10250 What does the "ST" used in the names of certain machine heads stand for (ST6, for example)?

"ST" is an abbreviation of "Standard Tuner"

FAQ10260 Do Schaller's sealed/enclosed machine heads need to be oiled from time to time?

All sealed tuners are lubricated with Schaller special grease, for a lifetime of maintenance-free service

FAQ10270 I have a MusicMan bass machine head produced by Schaller, and the shaft is slightly shorter than the original Schaller BM bass machine head. Can I replace the shaft?

Yes, you can use the Music Man shaft with buttons on the Schaller bass machine head and vice-versa, i.e. you can use the slightly longer Schaller shafts on the Music Man bass machine head.

FAQ10280 On which types of acoustic machine heads can I change the string posts myself, for instance when changing from a plastic sleeve to an emberger string post?

You can replace all open machine heads such as Hauser, Lyra, mandolin machine heads etc. yourself. However, you cannot replace the string posts in closed machine heads such as MK, MK Mini and Classic Deluxe yourself. Our emberger string posts with plastic sleeve and our nylon string posts are.
